This episode is brought to you by Rupa Health, Thrive Market, and Cozy Earth. Uric acid is a central player in metabolic mayhem. Despite its long association with gout and kidney stones, it’s involved in so much more—especially our metabolic disease epidemic. There are three things that raise our levels of uric acid: purines, alcohol, and fructose. The latter is the biggest challenge, due to its overwhelming presence in our Standard American Diet. That doesn’t mean all fruit is bad or even that all alcohol and purine-rich foods have the same effect. Like all parts of health and nutrition, there are nuances we need to consider to create optimal health. That’s why I’m so excited to take a deep dive into the topic of uric acid with my friend and colleague Dr. David Perlmutter. Dr.Perlmutter is a Board-Certified Neurologist and five-time New York Times bestselling author. He serves on the Board of Directors and is a Fellow of the American College of Nutrition. He is the author of Grain Brain among others, and his new book, Drop Acid was just released. Dr. Perlmutter received his M.D. degree from the University of Miami School of Medicine where he was awarded the Leonard G. Rowntree Research Award. He serves as a member of the Editorial Board for the Journal of Alzheimer’s Disease and has published extensively in peer-reviewed scientific journals including Archives of Neurology, Neurosurgery, and The Journal of Applied Nutrition.
